NOTE: Gray indicates insufficient data or a suppressed estimate.

The highest concentration of Non-Hispanic Asian residents in the Portland metro area is clustered in the Hillsboro area, where several zip codes reach approximately 20–30%, likely reflecting the influence of major tech employers such as Intel. Central Portland and Beaverton display moderate concentrations in the 8–15% range, while the southern and eastern periphery—including much of Gresham and the outer southwest—generally falls below 5%, creating a clear west-to-east gradient across the metro.
